2048776 - Use geo.provider.ms-windows-location in determining geolocation permissions

Status: NEW

(Toolkit :: Geolocation Provider, defect)

Description

[David Parks [:handyman]]

Network geolocation is not enabled on Windows. However, geo.provider.ms-windows-location is still "supported". That pref should disable geolocation on Windows and be reflected in permissions queries.

The pref should not engage the fallback network provider. This changes it to
report permission denial. When the pref is false, no doorhanger is ever shown
and no permission is ever given, regardless of any other state, such as
granted site permissions. The pref was never reachable from settings but was
mentioned on SUMO.

A lot of geolocation testing uses the NetworkGeolocationProvider, so we can't
completely block that off on Windows. Instead, the system will now validate that
geo.provider.testing is accompanied by a valid test URL (http://localhost,
http://mochi.test:8888, or https://web-platform.test:8888 are permitted).
